(100)/(010)- and (110)-oriented neodymium-substituted Bi4Ti 3O12 films were grown by metalorganic chemical vapor deposition on (101) and (001)RuO2 layers with a rutile structure. Epitaxial growth of the films with an in-plane c-axis orientation was confirmed by several X-ray diffraction measurements. Large remanent polarizations of 31 and 34 μC/cm2 were observed for the (100)/(010)- and (110)-oriented films, respectively. On the basis of the volume fractions of (100)- and (010)-oriented crystal estimated for the (100)/(010)-oriented film by X-ray diffraction, the spontaneous polarization of neodymium-substituted Bi4Ti3O12 along the a-axis was estimated to be 58 μC/cm2 from both kinds of epitaxial films.
